摘　　要：针对先导式安全阀工作时压力超调量大的问题,以电站锅炉用AF46Y-25先导式安全阀为例,在分析元件工作原理的基础上,利用AMESim仿真软件建立阀仿真模型,仿真分析先导阀阻尼孔面积、主阀弹簧腔容腔体积、主阀弹簧刚度、先导阀弹簧刚度对阀压力超调量等特性的影响。To overcome the pressure overshoot volume of pilot relief valve in operation,the valve simulation model,with a power plant boiler AF46Y-25 pilot relief valve being an example,and based on the analysis of working principle of the element,was established by the AMESim simulation software.The simulation analysis was conducted on the pilot valve damping hole area,the main valve spring cavity volume cavity volume,the main valve spring stiffness,and pilot valve spring stiffness impacts on the features of valve pressure overshoot volume ect.
